After visiting the Patriots on Monday, linebacker Rolando McClain and the team did not agree to terms on a contract, according to NFL Media Insider Ian Rapoport. The same report states that the visit was a positive one.

McClain played in 13 games last season for the Cowboys, collecting 81 total tackles and one sack. Over his four-year career, the 25-year-old has accumulated 327 total tackles, 7.5 sacks, 23 passes defensed, three interceptions and two forced fumbles.

Siliga is considered to be one of the top-two options at defensive tackle for the team after the departure of Vince Wilfork. The 24-year-old started five of the seven games he played in 2014. He recorded 32 total tackles and 2.5 sacks last season.

Hightower had surgery this February to repair a torn right labrum. The team is concerned that he might not be able to be ready for the start of the reguar season. He played through the injury for a good portion of the 2014 season prior to surgery.

The 25-year-old started all 12 games he played, collecting 89 total tackles, six sacks, two passes defensed and one forced fumble.
